Thanks, we have about 30 years at same location and know moving is a pain. Making slow progress on getting all our kids stuff out but the tougher part is thinning your own.
While I can foresee that issue in some locations, in my case, would get better amenities (swimming pool, workout facilities, party room, etc.) than have even in my current home. My woodshop would be another victim and speaker testing would be over (barely tolerated now). My kids will get first shot at the audio stuff so expect at least one will have a home theater and maybe some of my shop equipment. Along with the wedding, the tight market may slow us down. We are not in any huge hurry.
My wife and I bought a big family home in the suburbs as our first place together, and we never ended up having any kids. It took 13 years for us to figure out the house and neighborhood didn't make sense for us, so we downsized to a luxury 2 bedroom apartment downtown in the city with all the amenities, and then some. We sold/donated/tossed half of what we owned. It felt and was fantastic, for a while. However, as suggested in another post, downsizing was not at all what it was cracked up to be.
For me, any shared walls/floors/hallways were found to be the ultimate killer of joy in this hobby, and it turns out I just don't like sharing space and amenities in with other people that much, and all the stuff that comes with that life. If you don't know this about yourself, I highly recommend renting something first for two years to see if you actually like the lifestyle.
After 2 years we were back in a home, about the same size as the last one, except this time we were way smarter about it and built a house for
just the two of us instead of buying a home that was built for the average family. A wood & hobby workshop, a 12x16 yoga space with a built-in sauna at one end, a soundproof theater, and dedicated offices for each of us all take up space that is used quite differently in a typical home in our neighborhood. It turns out it wasn't so much the amount of space the was making us want to "downsize" last time, so much as it was how that space was used.
Something to think about anyway. You have plenty of time. You should start a thread.
